I see a lot of people saying they'd prefer a phone with a removable battery. Here's the thing: They exist, you have that option, everyone does and nobody takes it. Phones with removable batteries don't sell very well and that's why you don't see them advertised all over the place nor do you see manufacturers trying to pack in more features when it's not worth the effort for them. I know, everyone wants to believe the lack of removable batteries is so you'll be forced to replace your phone due to a dead battery instead of getting a new battery. I am going to tell you what my S/O who has sold this stuff for the last decade has told me repeatedly: They made a lot more selling extra batteries than they do selling replacement phones, there has been no notable increase in the rate at which people replace phones while we've made the move to non-removable batteries, and it's actually less common that people come in with complaints about their battery now than before as batteries now typically work well for as long as the average consumer uses their phone. It's also worth pointing out that, back when replaceable batteries were common, folks would often complain about the short lifespan of their batteries claiming they were being forced to buy replacements just to keep their phone on for a day at a time.
I know, I've been using the same phone for years, too. I could use a replaceable battery as mine is not holding a charge the way it used to. We are the minority, most folks don't suffer many ill effects from not being able to replace the battery in their phone. This situation is a fluke, and even after this you will only see a very small minority of folks talking about the need for replaceable batteries. The vast majority of consumers don't care about replaceable batteries and wouldn't really benefit from them.
